a Vented Enclosure with
Multiple Mounting Options
INSTALLATION/OWNER'S MANUAL
PREPARATION
Getting Started
Thank you for purchasing the Jensen JW10A 10" vented enclosure with built-in
amplifier. Although Jensen has attempted to ensure the information in this
manual is accurate, please be aware that any part of it is subject to change
without notice.
Please read entire manual before installation. Due to the technical nature of
amplifiers, it is highly recommended that yourJensen JW10A is installed by
a professional installer or an authorized dealer.
Before You Start
• Always disconnect the negative battery terminal. Consult a qualified technician
for instructions if you are unsure.
• Avoid installing the amplifier where it would be subject to high temperatures,
such as from direct sunlight, or where it would be subject to dust, dirt or
excessive vibration.
• Use extreme caution when drilling holes to avoid damaging fuel lines or
existing vehicle wiring.
• All amplifier installations require power, signal and speaker wires (not
included).
• An amplifier installation kit (sold separately) is highly recommended to
facilitate the installation. Consult your dealer for recommendations.
Mounting Location
Choose a mounting location for the JW10A. Suggested locations includebehind
a seat or in the trunk.
For optimum performance, make sure to provide at least 1" of space around all
sides of the amplifier.
Do not mount the JW10A under carpets or where airflow is restricted.
Do not install the JW10A where it may be exposed to moisture.
The optimum mounting location varies between vehicles. Remember to test all
amplifier functions before completing the final mounting procedure.
The following installation instructions are intended to be used as a basic
guideline. If you feel unsure about installing this speaker system yourself,
Jensen recommends acquiring the services of a professional car audio
installation center.
Before installation, please review the following guidelines:
1. Be sure to carefully read and understand the instructions before
attempting to
install this product.
2. If additional wiring is required, we recommend running all wires prior to
mounting your enclosure in place.
3. To ensure reliable performance and minimize signal or power loss, use
the
highest quality connectors available.
4. Never run speaker wires underneath your vehicle. Running speaker
wires inside the vehicle provides the best protection from exhaust, heat
and environmental elements.
5. Avoid running wires over, near or through sharp-edged surfaces. We suggest you
also use rubber grommets to protect any wires routed through metal, especially the
firewall.
6. When running the speaker cable to the amplifier, avoid running it near sources of
high current (i.e. wiring harnesses, battery cables).
Safety First
The following instructions are designed to ensure safety during
installation and use of the JW10A. Failure to heed these instructions can
result in injury or damage to the unit or vehicle.

Connection Descriptions
Note: Be sure to follow specific instructions included with your amplifier
installation kit (not included with this amplifier). The information below should be
used a general guideline only.
Power Wire (+12V)
• Disconnect negative battery terminal before proceeding. Consult a qualified
technician for instructions if you are unsure.
• Plan wire routing before cutting any wires to length. Begin by routing the power
++12V wire from the battery to the amplifier location. Use a grommet whe
running wires through the firewall or metal openings. Avoid running the power
wire near existing vehicle wiring to prevent induced noise from entering the
audio system.
• Use extreme caution when drilling holes to avoid damaging fuel lines or
existing vehicle wiring.
• The +12V wire MUST be fused within 18" of the battery for protection of the
vehicle’s electrical system.
Ground Wire (GND)
• The amplifier ground wire should be as short as possible. Choose a clean
unpainted section of metal or the vehicle chassis when attaching the ground
connection. Be sure to clean the area of any dirt or grease.
Remote Turn-on Wire (REM)
• The remote turn-on wire connects to the head unit's amplifier turn-on lead or
other switched 12 volt source.
Input Signal
• The amplifier's input signal connects to the receiver's low level (RCA) or high
level (speaker wire) outputs.
CAUTION
• Never run any wires underneath or outside the vehicle.

INSTALLATION
Main Power Connections
Connect BAT+, GND and REM wires accordingly. A suitable fuse MUST be installed on the
BAT+ lead within 18" of the battery for protection of the vehicle’s electrical system.
Fuse Rating
When replacing the fuse, make sure
new fuse is the correct type and
amperage. Using an incorrect fuse
could damage the amplifier. The
JW10A uses (1) 15 amp ATO style fuse.
Power/Ground Wire Size
For optimum performance, use only
12 gauge wire or larger. Make sure
to use the same size power and
ground wire.
High Level Input (Speaker Wire)
High level inputs should only be used when RCA
outputs are not available from the head unit. Connect
the head unit speaker outputs to the high level input
connector as shown below. The black wire (signal
reference ground) may or may not require a connection
to chassis ground - depending on your particular
installation. Do not use both low and high level inputs at
the same time. Connect only one or the other.

INSTALLATION
Control Setup and Adjustment
Low level (RCA) input signal is preferred for best
performance. Typical trunk-mount installations
require a 17-20 foot RCA cable. Most trucks and
behind-seat applications require a 6-12 foot RCA
cable. Using twisted pair construction RCA cables
will minimize noise.
The adjustable crossover is used to filter out
frequencies above 50Hz ~ 250Hz. Adjust it to where
the JW10A sound output blends with the rest of the
sound system.
The phase control compensates for delay between
the JW10A output and the rest of the sound system.
Begin with the phase control set to 0 degrees. If
the sound is adequate from the normal listening
position inside the vehicle, no further adjustment is
necessary. If the sound is thin or lacking bass, adjust
the phase control until the bass is full and punchy.
The input level control (LEVEL) is used to obtain the
best possible match between the head unit audio
output and the amplifier input. Begin by turning
the input level control fully counterclockwise. Next,
turn up the head unit volume control around 3/4 of
the way up. Adjust the input level control clockwise
until audible distortion is heard, then slightly
counterclockwise to provide the best match.
The LED indicator illuminates green during normal
operation.
